问题
I am implementing a change password ui, but when I change the password, the dialog that firefox's password manager displays to change the saved password doesn't appear.
I can't find the documentation on what is required for the form fields to trigger this behavior.
If anyone has the resource that goes through how firefox decides when to display the change saved password dialog that would be helpful.
